摘　　要：在油水井通井作业中,由于事先未知井筒套管已变形,传统的通井规易卡死造成事故,因此设计了一种新的多功能通井规。它能够克服传统通井规的缺陷,不会因套管变形卡死通井规而造成卡整个管柱;可以正洗井,而且排量足够大,不会因有脏物沉淀而卡通井规。During the drifting operation in producing and injection wells, the ordinary drift well gauge tool is easily stuck, which causes a serious accident because of unpredictable casing deformation. So an advanced drift well gauge tool is designed. It can eliminate faults of the ordinary drift well gauge tool. It can ＇t be stuck deadly and the whole string can＇t be stuck while the casing deformation is met. The conventional well cleanout can be carried out and the flow rate can be increased greatly, so the drift well gauge tool can＇t be stuck by the debris deposition.
